' To all 107mm it may concemr Beit known that I, Enwwm) L. AIKEN, a citizen of the United States, rcsiding'at East Oran 'e, in thecounty'of Essex and State of 5 New ersey, have invented certain new and useful Improvements in Phonographs, of

which the following is a description.

My invention relates to phono raphs'and similar-talkingmachines, on which provision 'is't'nade forautomatically stoppingthe rota tion of=the mandret'when t-heend of the record-has been reached, andmore particulnrly="-to" instruments ofthis: character in which a spring motor is used for furnishing tliedrivi'ng power.-

My-invcntion has for its dbj ect the appli cation of-snch means to phonographs as now built and on the market,- preferably in such i a way that the device will be for the most 5 part concealed so as not to detract-from the appearance of the-instruments" Myninnentlon also -ha s for 1t s' obJ eet jito plidr-for stopping-j; the spring motor will i ,1 also act-"es a frictional member for deter? \mining the speed'of rotatio'nbf:tlie 'inotor during thegoperatiori, of the instrument iVitlith'ese ends in view my invention conand'claimedl 1 4 Referenceiis hereby niadeto the swing nyingdrawing,1n which- Figurel isa plan and Fig. 2 a front ele- 35 ration showing indotted lines a phonograph of ordinary construction and in -full lines one form of device in which; lnyinvention may be embodied together with those parts of the phonograph to which ibis applied and with which it coiipcrates- In the device shown, a lever 1 is pivoted i at 2 to a lug, 3 sec red to or integral with the body of the instrument. The lower end of the lever extends laterally from the body 45 thereof and is formed with a socket-4 for 7 receiving a piece of felt or other yielding material 4' to be pressed against the face of the disk 5 carried in a well known manner by the' sleevefi of the governor shaft 7. During the operation of the instrument the lever 1 occupies the position illustrated in the drawing, whereby the felt at" is Withdrawn into such a position as to allow the motor to start and gain speed until the-face.

The lever l is normally held iiithe"'p0sitio'n'"jiown, by a rod 8pi'ifotet i" tliereto"at Sfan ,"entending' longitudinally"o f tli instrument. collar 10' \s'fixed" to an i errn'e dia't'e' portion of the rod andf'aflc'oihsprmg' 117siirrolinds' the same being pita-.5 lie tii fen the? said ..collar 'and tl ejgverticali eb" 12 the body of the inst-ru merit?

The pin .19 is always in migagement with the lever 17, and the latter is useful as i a hand lever for placing thespring under tension when, it; is desired to operate the i phonograph, It" can be dispensed with, if desired, :which therod 8 will carry a projection or ."shoulden for engagement f with the shoulder 2L of the latch 13. Ob-. viously the projection 15 may, if desired, be replaced by a. longitudinally adjust-able rod, so that the latch 13 may be tripped at any desired position with. respect to the recor tl I05 carried by the mandrel.

Itshould be noted that the at-t'aehmen. described is carried .entirely by the main mamas short am: it a at w engin -11a15%515 frame or body 0 of the phonograph and is not connected in any way with the motor frame a. The frame a is preferably floated between springs Z, I, so that vibrations set up by reason of the operation'of the motor and gearing will not be transmitted to the body of the instrun'lent, which means for supporting the motor frame is described and claimed in Letters Patent, No. 798,478, dated Aug. 29, 1905. Consequently, the insulation of the body of the instrument from the vibrations set up by the motor is not inter fered with by the application of the present invention to the instrument.-

Having now described my invention, what- I claim as' new and desire to secure by Letters Patent is:

1. In a phonograph, the combination of a body, a motor, a traveling carriage actuated thereby, a member rotatable by the said motor, a pivoted lever movable into engagement with said member, a longitudinally movable rod attached at one end to said lever and having its opposite end projected without said body, means within said body tending to move the rod lon itudinally a hand lever connected to said rod pivotally, a latch for normally holding the lever against the force of said means, said latch having an arm projecting into the path of the carriage,substantially as set forth.

2. In a device of'the class described, the combination of the motor having a sliding governor disk, a longitudinally movable rod, a friction pad adapted to engage said dish and connected to said rod, a spring applied to said .rod and adapted to cause the pad to engage said disk and stop the motor, and holding means connected to said movable rod, and comprising a hand lever for placing said spring under stress and a latch for holding said lever against the action of the spring, substantially as set forth.

3. In a phonograph or allied talking machine, in combination with the main frame or body carrying springs and a traveling sound box carriage, of a motor frame floated between said springs, driving mechanism including a motor, governor and governor disk carried by said motor frame, and releasable means carried by the body of the instrument and out of contact with the motor frame for pressing against said governor disk to stop the. motor, said means being released by the sound box carriage, substantially as set forth.

4. In a phonograph or allied talking machine, in combination with the main frame or body carrying springs anda traveling sound box carriage, of a motor frame floated between said springs, driving mechanism carried by said motor frame,-and releasable means carried by said body and out of contact with said motor frame for sto ping the motor, said means bein released by the sound box carriage, 'su stantially as set forth. 4

5. In a phonograph or allied talking-machine, in combination with the main frame or body carrying springs, and a traveling sound box carriage, of a motor frame supported by said springs, driving mechanism including a motor, governor and governor disk carried' by said motor frame, and releasable means carried by the body of the instrument and out of contact with the motor frame for pressing against said governor disk to stop the motor, said means-being released by the sound box carriage, substantially as setforth.

6. In a phonograph or allied talking machine, in combination with the main rame or body carrying, springs, and a traveling sound box carnage, of a motor frame supported by said springs, driving-mechanism carried by said motor frame, and releasable means carried by said body and out of contact with saidmotor frame for stopping the motor, said means bein released by the sound box' carriage, su 'stantially as set forth. 4
